Filed: 1973-07-26
Abstract: 1437434 Protecting semi-conductor switches against overload TOKYO KEIKO CO Ltd 26 July 1973 [26 July 1972] 35745/73 Heading H3T [Also in Division H2] In or for an inverter comprising first and second switching elements such as thyristors or transistors TR1, TR2, the control pulses for the switching elements are derived from a clock pulse source 16 by means of a pair of master-slave JK flip-flop circuits FF1, FF2 having their J, K and T terminals connected as shown. The pulses for the first switching element are derived from terminal Q2 of the second JK flip-flop whilst those for the second switching element are derived from an AND gate in response to the signals at Q1 of the first JK flip-flop FF1 and those at Q2 of the second JK flip-flop FF2. Spurious operations of the inverter due to irregular clock pulse frequency when first switching on is avoided by means of a time constant circuit R1, C3 feeding the clear terminal CL 1 of the first JK flip-flop FF1. Figs. 4A ... 4G (not shown) depict waveforms showing that when the switch 11 is first closed, the time constant R1, C3 prevents the flipflops responding to clock pulses until the frequency of pulses from source 16 has become stable. This action prevents saturation of transformer 10.

Abstract: 995,892. Refrigerators. GENERAL ELECTRIC CO. Sept. 26, 1962 [Oct. 11, 1961], No. 36540/62. Heading F4H. In a forced air refrigerator having a fresh food compartment and a freezer compartment cooled by a single evaporator, the humidity of air drawn from the fresh food compartment is reduced by passage over a section of the evaporator before this air is passed, with air from the freezer compartment, over the main section of the evaporator, thus preventing rapid frosting of the main section of the evaporator. As shown, the evaporator unit 3 comprises a housing 6 divided by a wall 23 into first and second chambers 24 and 25 respectively, the wall 23 stopping short of the bottom 27 of the housing to provide an interconnecting passage 28. A tube evaporator 5 within the lower portion of the housing lies partly in chamber 24, and partly in chamber 25, both sections having vertical fins which extend between the front and rear walls of the housing 6, the fins 31 in chamber 24 being more widely spaced than the fins 33 in chamber 25. A refrigerant accumulator 35 lies above the evaporator in the chamber 24. Air from the fresh food compartment, not shown, enters the top of chamber 24 through an inlet 20 and passes over the first section of the evaporator, most of its moisture being deposited thereon as frost. The air passes through the opening 28 and over the main portion of the evaporator in chamber 25, in company with air from the freezer compartment 1 which enters the lower part of chamber 25 through a slot 9. The cooled air passes from the housing 6 to a centrifugal fan 7 and thence by ducts 15 and 16 to the freezer compartment and the fresh food compartment respectively. The evaporator unit may be located at any convenient point in the refrigerator cabinet, and may be defrosted periodically by any suitable means.

Abstract: A mixture containing 2- and 4-chloro-m-xylenes is sulphonated and the crystalline 4-chloro-m-xylene sulphonic acid is precipitated from sulphuric acid of 80-100 (preferably 86-88) per cent strength; the precipitated product is separated and desulphonated by treatment with superheated steam in the presence of sulphuric acid to give 4-chloro-m-xylene.
